You can get compact cameras that shoot HD for that sort of amount. Depending on what you're doing that would likely do, but the mics tend to be a bit rubbish so might have a problem with sound recording.

In response: my brother has started making dumb videos with his pals and it looks fun so i want to copy him so I need a camera.
Is it really impossible to get a semi-decent camcorder for £150? Maybe I should wait till I get a job or something.
